<h2>Distribution connector <i>WINSTA</i>® MIDI 3-pole</h2><br/><br/>The <i>WINSTA</i>® MIDI distribution connector with protection against mismating provides the foundation for installation of fine-stranded and solid conductors. The pluggable installation connectors with spring pressure connection technology function without screw connections. They allow flexible, error-free installation in a large number of possible uses. The mechanical coding and color coding of the pluggable installation connector ensure error-free installation of the individual components – including protection against mismating. The pluggable installation connector is protected against ingress by solid objects in accordance with protection type IP20 (When mated: IP2xC (These compact connectors are not designed for use in open, easily accessible areas!)). The <i>WINSTA</i>® MIDI pluggable installation connector with A coding in white or black is usually used for general mains applications in power distribution. This pluggable installation connector is designed for a voltage load of up to 25 A. As a result, it can also be used for high power loads. The <i>WINSTA</i>® MIDI Pluggable Connection System with Push-in CAGE CLAMP® spring pressure connection technology facilitates exemplary electrification. Due to the integrated test slot, connections can be checked even when they are plugged in. That saves time and reduces installation labor and costs.<br/><br/><h3>Lower costs through fast commissioning and elimination of service expenses – solutions from <i>WINSTA</i>® MIDI</h3><br/><br/>The WINSTA® Pluggable Connection System is ideally tailored to the very strict requirements of building installation. It makes electrical installation pluggable, and thus more efficient, even more reliable, and error-free. Using this pre-assembled system reduces time spent on assembly and installation errors at the construction site. Now you can also cut installation expenses without compromising quality and safety: with protection type IP20 eliminates the need for servicing and prevents unnecessary downtime. <br/><br/><ul><br/><li>pluggable installation connectors with protection against mismating</li><li>pre-assembled versions</li><li>with A coding for a large number of uses</li><li>custom-engineered solutions</li><li>rapid, structured electrical installation</li></ul>
